IMPROVEMENT IN VENTILATOR ATTACHMENTS FOR COOK-STOVES.

Specification forming part of Letters Patent No. 204,819, dated June 11,1878; application filed May 18, 1878.

To all whom it may concern:

Be it known that I, JUSTUS HARDING, of Goshen, in the county of Elkhartand State of Indiana, have invented a new and valuable Improvement inVentilator Attachments for Cook-Stoves; and 1 do hereby declare that theI following is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

The drawing is a representation of vertical central section of myimproved ventilator applied to a cook-stove.

This invention has relation to improvements in ventilators for stoves.

The object of the invention is to collect the steam and other odorsarising from cooking and carry them through the smoke-fines into theopen air, instead of allowing them to be disseminated in the room andcondense upon the walls or ceiling thereof, to their manifestdisfiguration.

The nature of the invention consists in the construction and novelarrangement, in connection with a stove and its pipe, of a drum on saidpipe, a tube opening into said drum,

and turning upward therein, and a vaporgatherer on the lower end of saidtube, as

will be hereinafter more fully shown and described.

In the accompanying drawing, the letter A designates a stove, and B apipe leading therefrom into a chimneyflue, and provided, at a suitablepoint either in the vertical or horizontal part of the same, with anenlargement, O, resembling a drum, for a purpose hereinafter explained.

B represents a funnel shaped metallic vapor-gatherer, of suitabledimensions, arranged over the stove and connected to the pipe B by meansof a tube, D. This tube enters the pipe B at the drum C, after which itis turned upward, forming a short elbow, a, in the direction of thedraft from the said pipe, thus preventing the draft from the stove frombeing materially impaired, and creating an upward draft in the tube,that exhausts the odors and vapors caused by cooking from the room.

The drum 0 is of such a diameter relative to that of the pipe B and tubeD that the space adjacent to tube D therein left unoccupied by the saidtube is equal in dimensions and in capacity for carrying off theproducts of combustion to the said pipe Bthat is to say, if the interiordiameter of the pipe B is five inches and of tube D two and onehalfinches, the diameter of the drum should be seven and one-half inches, tocreate in the drum a flue of five inches.

The vertical portion of pipe D is made of one or more telescopingsections, b b, and at its junction with the Vapor-gatherer B is providedwith a winding-drum, J, controlled by a pawl-and-ratchct mechanism, bymeans of which and a chain, S, secured at one end to the drum and at theother to the pipe D, above its sections 12 b, the funnel may be adjustednearer to or farther from the stove, accordin g to the height of theculinary vessels seated thereon. This drum is actuated by a crank, 61.

L represents a damper arranged in tube D, and designed to cut off andregulate the upward current through the said tube, as required.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with a stove, A, its pipe B, and a drum, 0, on saidpipe, of a tube, D, opening into said drum and turning upward therein,and a vapor-gatherer, B, on the lower end of the said tube,substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

Jusrus HARDING.
